Application led .Tuly 8, 1919.

To all whom t may concern Be it kno-wn that I, JOHN E. DowDEN, a citizenof the United States, and resident of Lake Preston, in the county ofKingsbury and State of South Dakota, have invented a certain new anduseful Loading-Machine, 4of which the following is a specification.

The obj ect of my inventio-n is to provide a loading machine of simple,durable and inex ensive construction.

ore particularly it is my object provide a machine adap-ted to load allkinds of manure; hay or straw from a pile; and loose dirt, sand, orgravel onto a wago-n or other means of co-nveyance.

A further object isl to provide such a machine adapted to be furnishedcomplete except the engine, so that the owner may install any enginewhich he may desire when the machine is in use, thereby avoiding theadditional expense of an engine adapted for this machine only. l

Still a further object is to provide a machine comp-rising an elevatoradapted to lift the material to be loaded from the ground and to carrythe material to position where it may be dumped upon the conveyance.

Still a further object is to provide in c onnection with the elevator,agitating devices adapted to tear down the material to be loaded from apile and throw it on the elevator or to position where it may be readilypicked up by the elevator.

Still a further object of my invention is to provide means for adjustingthe vertical position of the lifting end of the conveyer and theagitating devices, whereby the conveyer may be regulated to remove thematerial to be loaded from uneven ground, and whereby the agitatingdevices may tear down material from the top of the pile as well as thebottom, to thereby avoid the danger of a portion of the pile caving inupon the elevator.

Still a furthe-r object is to arrange the machine so that all of theparts are mounted upon and driven by a single shaft to thereby lessenthe cost and increase the eiiiciency of the device.

`With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of thedevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and

Referring to the accompanying drawings,

Ihave used the reference numeral 10 to indicate the longitudinal framemembers of my device, and the reference numeral 11 to indicatetransverse frame members. v In front of the forward frame member 11 isan inclined frame member 12, which is: extended across to the left-liandframe member 10, at which point a. steerable caster wheel 13 is mounted.At. the right-hand rear corner of the frame is a caster wheel 14, and atthe left-liand rear corner is a traction wheel 15. The traction wheel 15is mounted on an axle 16, which is journaled in sup-ports 17 and 18 andcarries spaced bevel gears 19. f

Extended upwardly from the left-liand frame member 10 are a pair ofspaced parallel supports 20 and 21, havingbearings 22 at their upperends designed to receive a shaft 23.

Pivotally mounted on the shaft 23 between the supports 2O and 21 is anelevator 24 comprising spaced side wall members 25, a sheet iron apronmember 26, chains 27, slats 28 extended between and secured to thechains 27, and outwardly projecting pins 29 fixed in the slats 28. yAtthe forward lower end of the conveyer 24 is the driving shaft 30therefor, which extends outwardly and is provided with a sprocket 31 atits outer end.

Adjacent to the support 20 a large pulley wheel 32 is secured to theshaft- 23 and designed to receive a belt 33 which is extended throughthe pulley 34 of an engine 35 which is mounted on the frame of themachine. Adjacent to the pulley 32 on the shaft 23 a sleeve 36 isrotatably mounted, and sprockets 37 and 38 are secured to the sleeve 36adjacent to either end thereof. The sprocket 38 a chain 39 with thesprocket of the sprocket 38 will and cross bars is connected by 31 sothat rotation impart rotation to the chains of the eleva-tor 24.

A second frame designed to support agitating devices is also pivotallysupported upon the shaft 23, and compriseslongitudlnal frame members 40and 41. The inner end of the member 41 is pivoted directly upon theshaft 23 and is spaced from the elevator 24 and support 21 by spacingcollars 42. The inner end'. of the member 40 is pivotally mounted on thesleeve 36 between the sprockets 37 and 38 and spaced from the latter bysimilar spacing collars 42. The members 4() and 41 are rigidly connectedto each other by means of a transverse frame member 43.

A crank shaft 44 is journaled in the outer endsof the members 40 and 41,and a rock shaft 45 is journaled between the members 40 and 41intermediate of the crank shaft 44 and brace 43. Pivoted to the rockshaft 45 are guide members 46 designed to slidably receive bars 47 and48. The bars 47 and 48 are provided with strap bearings 49 adapted tocoact with the crank portions 50 of the crank shaft 44. Secured'to theouter ends of the bars 47 and 48 are agitating devices which will behereinafter more fully described.

At the end of the shaft 44 adjacent to the support 40 is a pinion 51designed to mesh with a pinion 52 mounted on a stub shaft 53 which isjournaled in the support 40. Fixed to the stub shaft 53 is a sprocket 54designed to receive a chain 55 which is extended over thesprocket 37.

From the construction of the parts just described it will be seen thatrotation of the sleeve 36 will impart rotation to the crank shaft 44 inan opposite direction to the rotation of the shaft 30 of the elevator24. Rotation of the crank shaft 44 will cause the agitating devices atthe ends of the bars 47 and 48 to move in a substantially oval path.

At the outer end of the sleeve 36 are notches 56 designed to coact withteeth 57 of a sleeve 58 which is slidably but nonrotatably mounted onthe shaft 23 by means of a pin 59 and slot 60.

At the outer end of the shaft 23 a sprocket 61 is fixed to the shaft andcarries a chain 62. vThe chain 62 is extended around a sprocket 63mounted on a shaft 64 which is extended forwardly to a gear box 65. Thegear box 65 contains change speed gears of ordinary construction,whereby rotation of the shaft 65 may be transmuted to several speeds ofthe drive shaft 66. The drive shaft 66 is provided with the universaljoint 67 and extends rearwardly to position adjacent to the bevel gears19, where a bevel gear 68 is fixed to the shaft 66. A link 69 ispivotally mounted on the shaft 66 adjacent to the bevel gear 68, so thatthe shaft 66 may be slid from side to side on the support 70 so that thegear 68 may be meshed with either of the gears 19 or held out of meshwith either of the gears.

From the construction of the parts just described it will be seen thatthe sleeve 58 may be moved to throw the elevator and agitating devicesinto or out of operative connection with the shaft 23 to thereby impartrotation to the former, if desired. lThe link 69 may be moved to impartrotation from the shaft 23 to the traction wheel 15 in either direction,or the shaft 23 may be disconnected from the traction wheel.

For controlling the movement of the sleeve 58 and the link 69 I providethe following means:

Adjacent to the rear end of the main frame 1 provide an upright 71, atthe top of which is pivoted a bell crank lever 72 having at one one endan elongated spline 73 designed to coact with an annular recess 74 inthe sleeve 58. Movement of the lever 72, therefore, controls themovement of the sleeve 58 and the connection of the shaft 23 to theelevator and agitating devices.

Extended through the support 71 near the bottom thereof, is a shaft 75having at its rear end an upwardly extending lever76. At the forward endof the shaft 75 is a downwardly extending link 77 which is pivotallyconnected to the right-hand end of the link 69. Movement of the lever 76throws the gear 68 into engagement with either of the gears 19 or out ofengagement with said gears. j

The gear box 65 is provided with an upwardly extending rock shaft 78designed when rocked to control the shifting of the gears within thebox. An upwardly and rearwardly extending link 79 is fixed to theright-hand end of the shaft 78. Pivoted to the right-hand side of thesupport 71 is a lever 80 which is connected by the link 81 to the arm79. Movement of the lever 80, therefore, controls the shifting of thegears in the gear box 65.

Fixed to the lower edges of the support 40 and to the lower edges of theelevator 24 are segmental worm gears 82 designed to coact with wormgears 83. The worm gears 83 are mounted on shafts 84 and 85 which arejournaled in a support 86 extended upwardly from transverse framemembers 87 of the main frame. At the right-hand end of the shafts 84 and85 are bevel gears 88 and 89. 1t will be seen that rotation of the bevelgears 88 and 89 will cause rotation of the worms 83, thereby causing aswinging of the supports 40 and 41 and the elevator upon the shaft 23.

Adjacent to the support 71 on the main frame is a second support 90having at aeeaeio either side adjacent to its upper end, `shafts 91 and92 journaled therein. At the rear end of the shafts 91 and 92 are xedhand wheels 93 and 94, and at the forward end of said shafts are fixedbevel gears 95 and 96 designed to mesh with the gears 88 and 89respectively.

It will thus be seen that rotation of the hand wheels 93 and 94 willcause vertical adjustment of the agitating devices and of the lower endof the elevator 24.

Journaled in the support 90 is a vertical shaft 97 having a steeringwheel 98 at the upper end thereof. A chain 99 is wrapped around theshaft 97 and around the shank 100 of the steering wheel 13, wherebyrotation of the shaft 97 may impart rotation to the shank 100 andcorresponding movement of the steering wheel 13..

The agitating devices mounted on the bars 47 and 48 may be of anydesired form to suit the work which is to be done. l preferably make thebars 47 and 48 out of flattened resilient strips of material and providecross bars 101 of similar material at their outer ends.

Fixed to the cross bars 101 in position spaced vfrom each other, aresubstantially parallel teeth 102 preferably also composed of resilientmaterial and provided with an inwardly' extending lug 103 having anopening therein designed to receive a rivet or bolt 104, whereby' theteeth may be secured to the cross bar 101. The teeth are also providedwith shoulders 105 designed to coact with the cross bar to furtherprevent displacement of the teeth.

Where the agitating devices are to be used for moving sand or wellloosened dirt to position where the elevator may act upon the material,a closure member 106 formed of light sheet steel or similar material maybe secured to the teeth by means of U-bolts 107, and an up-turned edge108 to change the agitating devices from forks into shovels.

Where the elevator 24 is of considerable length, an auxiliary supportmay be provided at the right-hand end of the machine, comprising a bar109 pivoted to the elevator 24 and slidably received within a guidedevice 110 which is pivotally mounted in the bracket 111 secured to themain frame. Set screws 112 may be used for locking the bars to the guidedevice 110 for holding4 the bars against movement thus holding the endof the elevator 24 supported.

In the practical operation of my improved device it will be understoodthat the machine is designed to be furnished as shown, but without theengine, so that the purchaser may use any engine which he may have, ormay use the machine engine for other purposes when he is not using themachine for loading.

ln order to compensate for variations in power and prevent breakage ofthe machine, 1 provide the belt 33 as a connection between the engineand the main shaft 23 so that some slippage may occur if necessary. Ifit is desired to load a pile of hay, straw or fertilizer with myimproved machine, the

one side of the pile until the entire pile has` been loaded. In thissituation it will be seen that when the center of the pile is reachedthere will be a tendency for the machine to dig in along the bottom ofthe pile, thereby leaving an overhanging ledge which would be liable tocave in upon the elevator and agitating devices, and possibly injure themachinery. By means of the adjustment of the agitator supporting frameit will be seen that the agitating devices may be moved to positionwhere they will tear down the material at the top of the pile so that nodanger will exist of a cave-in, and so that all the material picked upby the elevator may be thoroughly pulverized and broken up before it isbrought into contact with the elevator. The agitating devices may be soarranged that they will rake the material to be loadedl up upon theelevator if desired.

Some changes may be made in the construction and arrangement of thevarious parts of my device without departing from the essential featuresand purposes of my invention, and it is my intention to cover by myclaims any modified forms of structure or use of mechanical equivalentswhich may be reasonably included within their scope.
